Aye, Captain is a "glowing", complex chartreuse filled with varying hues of green and yellow. It's not pastel, but a semi-sheer sparkle shade much like Otherworld. Used over regular primer or blended over other shades, it is a great highlight or main color. But over a sticky base (or color base like black or white) it's a vibrant gleaming pop of color.
Worn here, with Chrome as highlight and Sorceress on brows, by beautful makeup artist Siryn.
